Source: Third Era

Source: Third Era is a "side fic" written by TheMissusD that spans forty-eight chapters and nearly reaches the length of the original novel. Based on the Third Era, or 'Equestrian Dark Age', it in turn inspired its own series of fan-fictions by other authors. It is told in different multi-chapter vignettes. Each vignette is the story of a different character that lived during various periods of the Third Era.
